“…Since the clinical course of ENKL varies depending on the stage of the disease, it is common that differential diagnoses, such as acute or chronic sinusitis, are considered early in the disease, as well as infectious processes of fungal etiology (fungal rhinosinusitis) with multiple treatments without improvement. Regarding disease progression, other differential diagnoses to consider in the presence of B symptoms include squamous cell carcinoma and nasopharyngeal non-keratinizing carcinoma, which are clinically similar to ENKL (only in immunohistochemistry), lymphomatoid granulomatosis, which is caused by B cells, and diffuse B-cell lymphoma in elderly patients, which has no regular involvement in the sinus or nasal areacv (3,5,12).…”

“…Although the etiology of this disease is unknown, some authors consider Epstein-Barr virus as an oncogenic factor because this infection causes neoplastic transformation of natural killer (NK) cells. Moreover, this herpesvirus has been found in almost all patients with ENKL and persists in studies in people with poor response to treatment (3)(4)(5).…”

“…La sepsis está asociada a una disminución de la perfusión de oxígeno a los tejidos, debido a la vasodilatación que genera, sin embargo la presencia de la E. coli hace suponer que también su endotoxina contribuyó a la necrosis periférica del paciente descrito; en nuestro caso la paciente presentaba LNH de células T-NK, lo cual ante el cuadro de inmunosupresión por la neoplasia la predispone a obtener alguna infección, y esta aumenta el riesgo a ser susceptible a la acción de la endotoxina en el organismo, ocasionando probablemente la placa necrótica (14,15) .…”

“…En el reporte de caso de Castro BJI, se evidencia una lesión similar, pues describe una induración necrótica de fosa nasal derecha asociado a secreción seropurulenta blanquecina fétida de 3 meses de evolución, sin embargo a los exámenes microbiológicos se descubrió que fue de origen micótico, en el cuál también hace su enfoque en la rareza de infección en la zona mencionada (15) .…”
